A tlangpi in
Hmuh khawhnak lei ah a dang tein chiahmi himnak khamnak: PHD-12TF-288, digital luhternak le chuahnak, luhternak pakhat le chuahnak pahnih.
^ A dang tein chiahmi dawnkhantu nih ttihnung hmun ah a naihnak thlennak le pehtlaihnak luhternak kha transistor chuahnak signal ah a thlen khawh i a himnak hmun ah a kuat khawh. Ec karlak i a chuakmi transistor cu "inverted phase/normal phase" timi thimnak thlennak he aa tlum, cu pin ah, luhnak signal short circuit asiloah open circuit alarm indicator a um, circuit nih luhnak sensor thazaang peknak a pek.
^ Hi thilri nih hin lenglei 20-35VDC thazaang peknak a herh.
^ Signal dirhmun langhtertu cu chuahmi relay riantuan ning langhternak caah a sen le a senmi ceunak in chiah a si, ralrin peknak caah a si tikah ceunak cu a sen, a ttha tein riantuan lio ah ceunak cu a sen.
* Bus thazaang peknak, a tawinak caah appendix zoh.
